Hi,
I am making a script and need to know when the computer was last booted.
This can be done with
who -b command. I have installed the minimum cygwin and this command is not
available.
Which package do I need to install in order to have this command available
(or any other command
that can tell when the computer was last booted).
Kind regards, Peder

If you have 'SystemInfo' you could try:
$ cmd.exe /C "SystemInfo /FO list" | grep 'System Boot Time'

The procps-ng package provides the uptime command which will tell
you how long it has been since the computer was last booted.

FWIW
on my cygwin, 2.11.0(0.329/5/3), I have who (GNU coreutils) 8.26.
Of all the options -a/--all gives:
$ who --all
roger - pty1 2018-10-16 13:05 . 276 (10.40.90.15)
-u, -H, -m, -s, -u gives the same (plus/minus a '-' or '.')
-q seems reasonable, at least similar to the same command on fedora
--version, --help give expected output.
The rest return nothing, including -b

You can do an online search[1] to determine which package to install to
get a binary. In this case who.exe.

/var/run/utmp system startup/shutdown records are not written so who -b shows
nothing although who is included in cygwin Base package coreutils
/proc/uptime shows number of seconds wall time since startup, and number of
seconds idle time since then e.g.:
$ cat /proc/uptime; date -d"now - `cut -d' ' -f1 /proc/uptime` seconds"; uptime
